According to a recent study in the New England Journal of Medicine, losing weight is "basic physiology. Eat fewer calories than you expend." This sounds like advice we’ve heard before, but this time it’s a little more black-and-white. To quote one of the organizers of the study: “People do have to choose heart-healthy foods. I think the beauty of the study is that they have a lot of flexibility in terms of the dietary approach."

In other words, eat what you want that isn’t junk. Just don’t eat too much of it.
